To all whom it may concern:

Be it, known that we, SEDNEY 'i'nlioxo and li'llht) (l. ,'-u.minc'ri'r, ciiizens dithc United Si JiCS, residii'ig lil Minneapol is i n the county of ll cnncpin and Stiilc of :Miimesolc, 11m invenlcd certain new and useful improveinonfs in Envolop and (lard Feeding lllceiiuni n; and we dohcreliy dcclcre ilic following to he 12 $1111, clear, and exact description of the invention, such will enable others skilled in the art to which it apperioins to make and use the some.

This ini'enlion has for iis primary object to providc a highly cliicicnt' and perfectly reliable mechanism for selccl'ing and i'oi' feeding; envclop's, one iii :1 time, from a pack, and for opcning l'hc llaps thereof, so that (hey are in proper condition for delivery to coi'i ticrai-ing moisi'cning and sealing; devices.

To lhe chorc ends generally slated, the invention consislsol the novel devices and eoinhinoiions oi devices hcrcinzii l'cr dcscribed and defined in the claims.

The selocl'ioi'i of m rions kinds of envclcps ins dii fcrent'lozuls or concnts, "from or pack orsiacln and feeding Cit . v f v il'iere'lron'i, one at n time, with llieir guninied flaps opened up in pro'per condition for n'io1sl'cnmg,lms been found nglremcly illiil- G cull. in he first piiicc llic' envclcps lhcniseli es vary greaily in'chiilrocller. Soi'nc arc of flimsy, light nmtcrial, and some of very slid materialp Some, ihcrcol are provided \viih address openings covered. will) ironsparent material, and some are simply providedwith open slots in their faces through which. an address on the inclosed letter or card may be seen. Sometimes the envelops will contain only a simple lcl'tcr or card and at ol'her times they will containhnlliy matfcer, such as a large number of advertisin folders, cards, and even small articles 0 j gncrehnndisc.

Ourinveniion.provides a separating and feeding mechanism which will, :vviih certainty and accuracy, handle the various kinds of cnvclops, regardless of their contents. In accordance with the invention, the envclops are placed in a stock or pack 1n a holder or magazine, which at the centiol portion of its loot-tom or delivery end, is open. Qther viso stated the said bottom ofjlghc magazine or holder is provided with shun moms or envelop supports that are spaced apart longitudinallyof the line oi feod, iind transversely of the envelope; that one 'lnced wiiliii the magazine. A soitaiily equipped dcvice is applied lo the magazine, ndjocont to lhc envelop support which is of, the; equipped edges of the cnvelops. The en velop flops are primarily folded.

The envolcps are separated and from the magazine, one at a time, by an oscillating or ri'irieiprocnling member provided with reverscly acting; lingers, one oi. which forced helix-oer; ihe flap and body of she lion tom envelop n'fhd 'inl'o engagement with the hose of tho izip', anal-is; sensed to imgisirl 331iinary movement to he said envelop in one direction, snilicicnl' i0 carry the some beyond lhc cscapcmontdevice and oni of engagement with the envelop supporting abutment or lodge which is at the opposite side of ihe imignzine. 'lhc so-collcd primary sen ors-h in linger, above noted, performs the operalion just described under movement of the feeding device in one direction, and "under moven'icnt of the coding device in. the other direction, the so-called secondary separat ng 7 finger engages the envelop and imparts a sccondany movement thereto which entirely V rcinovcsfihe selected envelop from the magnzinc and starts lhc some on its Wily to the moislcning and sealing devices and under Referring to the drawings, Figure 1 is a' side elevation with somoparvs broken sway,

Fig. 7 is a detail view of a modification of the primary feed finger.

' hereinafter used in this specification and in the claims, the term envelop feeding device" nisni which selects and squat-ates the envelops, one at a time, from a pack, and feeds the same from the magazine." Such feeding device is capable of many uses. but is especially designed and intended for use in an envelop sealing machine, and in the drawings, it may be assumed to be thus applied. The framework of the envelop sealing machine is shown as made. up of laterally spaced hearing plates l, rigidly tied together by transverse bars 9 and 3, and other devices, not shown.

The numeral 4 indicates cooperating feeding rollers to which the envclops are delivered from the magazine by our-in'iprm'ed feeding device. These rollers 4 may he issumed to be continuously driven, and to be separated and moved togetherwith a prop erly timed action as, for instance, in the manner di.-: .-losed in the co-pending appl'icai tion of ..\lhrecht and Long, .5. N. (322.25%, filed April it), l)l'l.,and entitled llnvelop sealing marhincs. So far this invention is conwerned. they are cooperating envelop feeding rollers adapted to pass the envclops delivered thereto, onward to cooperating devices, such, for instance, as moistening and sealing mechanism.

[u na-clap 1nage2mc.-llic envelops a with their gunnned flaps a folded, are arranged in a pack or stack within amagazine which is preferably tnadc adjustable to envelops of dilfcrent -lengths and widths. The envelop magazine ln-cterahlyinclined. The flapeq'ui'pped edges of the en elops are placed fand t, the retaining bars are provided ,forward against confining bars 5 which may he rigidly secured to the frame cross bar 2. The front cdgcsof the pack of cnvclops are supported by an ahutn'icnt G which is conveniently secured to the tran'leeross har The upper surface of the supporting abut ment, 6 is preferably rounded, as clearly, The. lower edge 3 shown in 3A: and portionsof the envelops a are supymrted on an abutment or ledge 7 showp as 'l'orn'ied in tegrztl with a hanger plate 8, rigidly atis used to designate a. meeha-.

that thelowermost envelop of the stack will engage only the edge of ledge 7 and practically a single element of abutment 6, the curvature of which falls away from said engaging point, the whole arrangement being 7 adapted to permit ready separation of said lowermost envelop from the remainder in the stack, as will hereinafter appear. The hanger 'rods 10, at their extreme upper ends are pivotally attached to a relatively fixed support 11 (see Figs. 1 and 2). At the rear, mounted in suitably journaled hearing plates 1, at the rear of the hanger plate 8, is a i transverse rock shaft 12 provided atits intern'tediate portion with an arm 13 that is connected by a link 14 to the upper portion of the hanger plate 8.

The numeral 15 indicates a guide or retaining arm which is rigidly secured to the upper portion of the hanger plate 8 and the inclined upper portion of which maintains engagementwith the lower portion of the shaft 19 under different adjustments of the hanger plate 8, and thereby holds the said hanger plate against upward jumping movements. The rock shaft- 12 is adapted to be set in different adjustments by means of an arm rigidly secured to one' outer end thereof, and'provided with a latch 17 that is engageahle with any of several perforationslS in the adjacent bearing plate 1. By adjustments of the arm 16, the hanger plate 8 may he moved laterally toward or from the fronthars 5, so as to thereby vary the width of the magazine and set the same to properly we hold envelops of different widths.

The escapement device employed for preventing more than one envelop from being moved at one time from the magazine. may take different forms, but is preferably of the character disclosed in the ctrpe nding application of Albrechtand Long. above identified. As indicated most clearly in Figs. 2, 3

; are escapcment members 19. connected with flanges 5 by means of links 20 pivotally connected at one end to the said flanges and at the other end to the cscapemcnt bars 19,

;the links preferably extending in an uptached at its upper portion, at. l). to thei lower ends of the escapemcnt bars 19 are lower nd of a pair of hanger rods 10. The

ing point on the curved surface of abulin nt 6 is preferably positioned with respect to the supporting edge of ledge 7 so that the envelop will be held ina positiou slightly oblique to bars 5 and hanger plate 8. which \vardly oblique direction from thevpoint of connection with the flanges to the point of count-(lion with the cscapement bars. The

provided with depending stop lingers 21, which may he rcmwardly curved and normally rest upon downwardly curved rest bars 23, said rest bars having the portion of their surfaces thus engaged below the envelop supporting portion of abutment 6, the red bars 23 being secured in position to the latter members will of course be relatively ,l'rame crossbar 3.

This structure, as shown, is such The end plates 24 of the envelop maga- 13o movements of the fingers 41, in respect to zine are made adjustable to envelop?v of difgears, although their teeth are indicated in erabl 1 made 1.1) of two aai ts 3"? and 37 step acre :terent lengths and, as shown/a with hub portions n'iountod t bar=2 and con taneous reyerse moveinen y a, "lazy tong 26. The lazy tongis intierinedfiately pivoted to the bar 2 at 27 and'isflcliuectly connected to sliding hubs E by metal stra 28. Under all adjustments or the "end plates :24, the envelope, lregardless of length, are kept centered in irespect to the machine. The supporting ledge or abutment 7 of the magazine is shown as provided with one or more rearwardly projecting spring fingers 7, under which the envelope are fed to the rollers 4.

l ac/Hay] '?'/I.( /I (lTI liS7)6.-*l11 the illustrated, and what is at present thought to be the preferred ft'orm of envelop feeding mechanism, aroek shaft 29 is mounted in the frame bearing plates 1 and at one outer end is provided with an arm 30 connected by a link 31 to a crank pin of a gear This gear is shown as journi-iled to the ndjacent bearing plate 1, and is in mesh with gears S'azid 35, also journaled to the said bearing plate. Tihese gears are all complete part by dotted lines in Fig. 1. In one Way, or another, not necessary for the purposes of this ease'to consider, the gear 33 is driven from one or the other of the said gears 34 and 35, so that the rock shaft 29 will con tinuously oscillate. At its central portion, the rock shaft 29 is provided with a feed arm 36, to the free end of which, the reversely acting primary and secondary teed lingers are applied. Preferably, the reel: shaft 29 is provided with two of the said arms 36 and primary and secondary selecting' or feeding fingers applied to ehch. I, The so-ealled primary selecting fingers are prefboth of which are pivoted to the cooperating arms 36 at 38. A slot and pin ctnn'iection 39 permits slight pivotal moyeincnt of the said parts and 37 in respect to each other, and they are yieldingly held in. the relative position, in respect to each other, shown, for instance, in Fig. 5, by a light. coiled spring- 40. The so-callod secondary selecting fingers 4-]. are pivotnlly connected to the cooperating arms 36 and 42- and tl'iey; are provided with forwardly and upwardly projcctin hooked ends 43. 'Extremeoscillatory the arms which carry them, maybe adshown as'applied to lugs 4.5 carried by the said arms 36. Light coiled springs 46 (see fingers it and to the corresponding arms 36, yieldingly hold the fingers againstthe we aid. The upper ends of the we fingers it ar onrr cle d are ranged-to be thrust against cam acting abut ments 47 secured on the frame bar 3, tor a purpose which will appear in the description of the operation. The extended ends of the supplemental sections 37 of the prii'nary fin gers 37 are connected to a cross rdd or sleeve 48 that is extended through an llregrulal' cam groove 49 of a fixed cam block 50, through which, as shown, one of the frame tie rods 51 is passed.

The numeral indicates fingers pivotally supported at 53 and which may be assumed to be yicldingly pressed upward so that they cooperate with the spring fingers 7 to guide the envelops between the rollers 4. The above noted t'ururtion is all that need to be mentiiined here in respect to the said fingers 2,:1lthough, in the complete machine, they perform another and more important function. it. may be here further noted that the feed rollers 4 are preferably groojved so as to permit the miners 52 to -be pressed downward, as shown in Fig. 5.

O1 amtion.-lVhat may be assumed to be the normal positions oi the primary and secondary selecting fingers 37 and 41, is indicated by dotted lines in .Fig. 4-. From these positions, the said fingers are first moved'imward and toward the right, in respect to Fig. 4, and the first result of this that the points of the primary fingers 37 are forced between. the flap and body of the envelop which isnt; the bottom of the stack, the

sharp points (it the said lingers R7 lightly scrape along the lower surface of thhbottom envelop, and hence, are certain to pass above the gununed flap thereof, and to thercby positively force the flap into a partly openedposition; and under continued up "ard movement, the said primary fingers, engaged as stated, force the bottom envelop from the bottom of the stack toward the right, and under the gravity-- held yielding; escapen'ient device Ill--20. This tiist movement oi the envclo 'i, which may be desig noted as its primary l'novolnent, carries the lower edge thereof beyond and ofi from the supporting abutment or ledge 7, as clearly shown in Fig. 3, the position shown in Fig". 8 being the extreme position of the said tingers 37 and all, in a. forward and upward position toward the right, in respect to Figs. 3, 4 and The free part of the envelop under the influence ol gravity and from the pressure of the stack above, will drop down upon the rest bars 23 into the position shown in Fig. 3, where the lower edge will stand out separated from the body of the stack in position to be guidcdby spring fingers 7 when moved by the feeding means in reverse direction. Under the primary movements, ju sgt stated, the tie bar or rod 48 moves in the ean'igroooe 4-9 on such irregular line that it causes the points of the primary fingers 37 to move in approximately straight lines he tween the position ind cated by dotted lines in Fig. 4, and the position indicated in Fig. 3. The spring and slot and pin connec tion 39 pe 'mit such sliq'ht variation from its straight line movement as may be required to insure the close contact between the points of the said primary fingers and the body of the bottom envelop of the stack. When the feed arm 36 given a movement required to impart the above deseribed primary movement to the said fingers 37 and 4-1, the curved ends of the latte' are thrown against the cam acting abutments at? and are forced upward, against the tension of the springs, 46 so that in the position of the parts shown in Fig. 3, the l'moked ends 43 of he said seeondaryfingers stand. above the upper edge of the partly ejected envelop and so that when moved backward, or to ward the left. and downward in respect to Fig. 3, thesaid hooks are certain to engage the upper edge of the said partly ejected envelop.

The secondary or second step of ejecting movement is imparted to the envelop by movement ot the arm 36 and ejecting tingers 37 and 41 toward the left and downward, in respect to 4 and 5. Under this movement. the primary fingers 37 re- "eede from their engagement with the face of the envelop liap and the hooks 43 of the fingers -11 are moved into elose engagement with the upper edge of the partly ejected envelop and draw the engaged edge'portion thereot', slightly below the upper face of the abutment G. which at that time, supports the upper edge portion of the said envelop. The.

lower edge. of the envelop at this time. as alremly stated. is dropped below the lower supporting abutment 7 so that under (ontinued inorement downward and toward the eft. the envelop engaged thereby will be positively earriml from the bottom of the stack and delivered between the rollers 4. and under this delivering; movement, the primaryfingers 37 maintain engagementwilh the gunnned flap ot' the. envelop and turn the same into an opened position. Fig. 4 shows the envelop moved about half way from the position shown in Fig. 3, toward the position shown in Fig. 5, and the aid latter view shows the envelop, with its llap opened. delivered between the said rollers l and the said rollers operating: to continue. he teed movement of the said envelop. The light spring fingers T simply prevent the lower end of the envelop t'rom being tilted upward into position too high for proper delivery between the rollers l. Attention is here further called to the tart that under the above desrrihed so-ralledsecondary teed movements. the hooked ends 43 of the tin- ,YILIS ll aroengagcd with the rpper edge of the )artlv e'ected envelo before the curved ends of thsaid fingers leave. contact with the cam abutments 47, so that the proper initial engagement is insured; that the disengagement of the said fingers from the said abutments 47 takes place before the hooked ends 43'tl1ereot'. are moved forwa rd far enough for possible engagement with the envelop lying inm'iediately on top oi the partly ejected envelop; and that immedi ately after thedisengagement of said tin- ;"ers -tl from the abutments t7. the springs -l(3 draw the hooked ends thereof downward.

moving the engaged edge portions of the envelop therewith so that they have good clearance from the upper edge of the evelop next above the partially ejected envehrp. Thus. there is no possibility of the secondary fingers ll taking up two envelops at one time.

The important features of this improved envelop eeding mechanisn'i summed up are substantially as follows: The envelops are ejeeled from the magazine by movement first in one direction. to disengage the same t'rom the supportingabutment or ledge. of the magazine, and are then moved in a verse direction to disengage the envelop from the other or second supporting abutment or ledge of the magazine. Stated in another way, the envelops are ejected. one at a time. through an intermediate delivery passage in the bottom of the niapjiizine. .\n eseapementdevice and cooperating es ape passage permits the initial movements at the. envelops, one at a time. so that they may be ejected through the said intermediate discharge passage ot'the magazine. The envelops are ejected by deviees that engage. the flaps thereof. so that neither the contents, nor the construct ion of the body of the envelop interferes with the ejecting action of the sci-called primary and secondary ejecting lingers. The primary fingers that engage the envelop flap to ettect the primary Alls"lltil'f "t movement there f, serve to open the envelop flaps, while the envelop is given its secondary or reverse movement. by the so-ealled secondary fingers.

Any kind of mechanism arranged to aceomplish the discharge or (jet-ting movements of the envelops from a magazine in the manner above described, will be within the seo'pe of our invention. From a broad point of view. the combined 0 ieralin n'i mary and secondary lingers atl'ord a 'sort ol a grapple'or nincers that embrace or catch the llap of the envelop and eltev-t the deliv ery oi. the envelop by the two-step reverse movement, above 4 le.- .erilu d.
